Missing return in a function

Hi,

I'm getting an error but I don't know why. Copied what was done in the course but I'm getting "Missing return in a function expected to return [String: AnyObject] when the return type is specified. Why?

class PlistConverter {
    class func dictionaryFromFile(resource: String, ofType type: String) throws -> [String : AnyObject] {

        guard let path = NSBundle.mainBundle().pathForResource(resource, ofType: type) else {
            throw InventoryError.InvalidResource
        }
        guard let dictionary = NSDictionary(contentsOfFile: path),
        let castDictionary = dictionary as? [String : AnyObject] else {
            throw InventoryError.ConversionError <-- Error here 
        }

        return castDictionary
    }
}

Copied what was done in the course but I'm getting an error "Missing return in a function expected to return [String: AnyObject] when the return type is specified. Why?

Thanks,

Julien

Tbh, I cannot see an error in the snippet you posted... Have you tried clearing derived data and the build?

I just made the build and it disappeared...
